Astronomers suggest that the solar system is about 0.5 light year long or possibly even a full light year. The debate is not settled due to the Oort Cloud ( it is an entire cloud made up asteroids closing the solar system) and astronomers say that the Oort Cloud could be 1 light year in length.
Here is a list of useful constants: 1 Solar Radius = 6.9599 10 cm = 6.9599x10 8 m (Equatorial) 1 Moon's Mean Orbital Radius = 384,400 km = 3.8440x10 8 m 1 AU = 1.4960x10 11 m = 1.4960x10 8 km (Astronomical Unit) 1 ly = 9.4605x10 15 m = 9.4605x10 12 km (light year) 1 pc = 3.0857x10 16 m = 3.0857x10 13 km = 3.261633 ly...
The solar system is a pin prick compared to these sizes. i.e. 1 light year is about 10 trillion kilometres... share: To measure the width of your solar system you use what?
The diameter of the solar system is approximately 7,500,000,000 miles and light travels 5,865,696,000,000 miles in a year, so the diameter of the solar system is about 0.0013 light years.
Now, 1 light year is 63,270 AU, which means that the distance to the nearest star is 272,061 AU. We took the radius of the solar system to be 39.5 AU, which means it has a diameter of 79 AU. This means you could put the Solar System about 3440 times between the Sun and the nearest star taking this definition.
The volume of space lying within 20 light-years of Sol encompasses over 33,509 cubic light-years. Within that vast sphere, astronomers have been able to detect at least 50 Solar-masses of visible matter bound up in 138 luminous stars and weakly glowing white and brown dwarfs thus far.

And 1 light year is 63,270 AU. Now let us put things into perspective. We took the radius of the solar system to be 39.5 AU, which means it has a diameter of 79 AU. This means you could put the Solar System about 800 times in one Light Year.
The light-year is a unit of length used to express astronomical distances and measures about 9.46 trillion kilometres or 5.88 trillion miles. As defined by the International Astronomical Union, a light-year is the distance that light travels in vacuum in one Julian year. Because it includes the word "year", the term light-year is sometimes misinterpreted as a unit of time. The light-year is most often used when expressing distances to stars and other distances on a galactic scale, especially in
At this speed, it takes around 1,190 years for the Solar System to travel a distance of 1 light-year, or 7 days to travel 1 AU.
